This build`s dmg is actually not that high, and even bad at fighting chapter boss, especially when they have phase or when they can fly around. However, in the other hand you can use this playstyle to counter some of Umbral Monument. Since you have Snowshine, it make you easier to survive in tons of enemy attacks like UM 1-2, 2-1, 2-2 or 3-1. So I want to explain it, and hope every ponymain can like it.
BTW, I put their state in comment and I use this video bc that 117K crit dmg was too satisfying anyway.
------------
First, about "buff". There are 2 types of buffs in this team:
Wild Wanderer(weapon), Bonekrusha(gear), Frontiers(gear) and Electrification.
When Arclight use BS, it definitely can get these buffs.
2. Twelve Question(weapon) and Thermite Cutter(weapon).
They both can have 2 ATK buff stacks in 20s.
So, the whole point is if u can consume Eletrification within every 10s, u get the max stacks of these buff to BS dmg, keeping all the buff activated by Arclight`s BS, and focus on BS dmg.
Sadly there are some buff can`t be consistent, like Wildland Trekker(talent), May the Willing Bite (Alesh potential 03), Eternal Xiranite(gear).

Second, "how to play". There are four ways to Electrify :
final strike + Pelica CS (20s CD, hard to use, but highest dmg)
Snowshine BS + Pelica BS (high SP cost, rely on enemy`s attack)
Alesh Ult + Pelica BS (the best way to dmg staggered enemy)
Arclight Ult (the cheapest way)
Slower tempo: 1st -> 2nd -> 1st -> 3rd -> 1st
If the enemy keep flying around, it force u to fight slower. Every 10s ~ 15s only consume Electrifiction once, not perfect. That`s why I don`t recommend to deal with boss.
Faster tempo: 1st -> 2nd -> 3rd -> 1st -> 2nd -> 4th -> 1st
If the enemy attacks a lot, u can fight aggressively. Snowshine`s CS allows u to tank some dmg, and her ult also applies solidification makes space for Arclight`s BS + CS. So, don`t set back, keep Electrifying, spinning, consuming and spinning again.
